'function' object has no attribute 'name' when registering blueprint

Question

Here is my project layout:

baseflask/    baseflask/       __init__.py       views.py       resources/           health.py/    wsgi.py/ 

Here is my print

from flask import Blueprint from flask import Response health = Blueprint('health', __name__) @health.route("/health", methods=["GET"]) def health():     jd = {'status': 'OK'}     data = json.dumps(jd)     resp = Response(data, status=200, mimetype='application/json')     return resp 

How I register in __init__.py:

import os basedir = os.path.abspath(os.path.dirname(__file__)) from flask import Blueprint from flask import Flask from flask_cors import CORS, cross_origin app = Flask(__name__) app.debug = True  CORS(app)  from baseflask.health import health app.register_blueprint(health) 

Here is the error:

Traceback (most recent call last):   File "/home/ubuntu/workspace/baseflask/wsgi.py", line 10, in <module>     from baseflask import app   File "/home/ubuntu/workspace/baseflask/baseflask/__init__.py", line 18, in <module>     app.register_blueprint(health)   File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 62, in wrapper_func     return f(self, *args, **kwargs)   File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 880, in register_blueprint     if blueprint.name in self.blueprints: AttributeError: 'function' object has no attribute 'name' 

Answer 1

You masked the health global name referring to Blueprint instance, by re-using the name for the view function:

health = Blueprint('health', __name__) @health.route("/health", methods=["GET"]) def health(): 

You can't have both the route view function and the blueprint use the same name; you replaced the global name health that referred to the blueprint and are trying to register the route function for the same global name.

Use a different name for the blueprint:

health_blueprint = Blueprint('health', __name__) 

and register that:

from baseflask.health import health_blueprint app.register_blueprint(health_blueprint) 

or use a different name for the view function (at which point the endpoint name changes too unless you explicitly use endpoint='health' in the @health.route(...) decorator).

Answer 2

health = Blueprint('health', __name__) @health.route("/health", methods=["GET"]) def health(): 

Your blueprint name is same with your function name, try to rename the function name instead.

health = Blueprint('health', __name__) @health.route("/health", methods=["GET"]) def check_health():
